“…A total of 180 common bean accessions and 3 commercial cultivars collected from 19 Turkish provinces were used as plant material in this work. The commercial cultivars (Akman, Goynuk, Ksracsehir) used in this study were developed through the single plant selection having resistance to various diseases and have been used as standard cultivars in several other studies [25,26]. The accessions (landraces) were previously collected from farmers' field (Table S1, Figure 1).…”

Plant landraces represent a repository of a gene pool, local adaptation of their domestic species, and thereby are considered a great source of genetic variations. Such genetic variation can be helpful to mitigate the current and future food challenges. A total of 183 common bean accessions including three commercial varieties collected from 19 Turkish provinces were grown to record their morpho-agronomic variations and to evaluate the best performing accessions under multi-environmental conditions. Plant height, days to maturity, pods weight, seed length, and 100-seed weight were used to evaluate the best performing accessions under different environmental conditions. A wide range of variations for traits like days to maturity (99-161), plant height (21-168.7 cm), seed length (7.41-16.4 mm), seeds per plant (17.8-254.4), and 100-seeds weight (24.97-73.8 g) were observed and can be useful for breeding purposes. The analytic results derived from the first three eigenvectors suggested that plant height, plant weight, 100-seed weight, and days to flowering were biologically significant bean traits. Seed yield per plant was positively and significantly correlated with plant weight and pods weight. Genotype × environment biplot discriminated the studied common bean accessions based on their plant height and growth habit. Plant height, days to maturity, seed width, and first pod height were found highly heritable traits and were least affected by environmental forces. Among 19 provinces, accessions of Bilecik showed maximum pods per plant, seed yield per plant and 100-seed weight, while Erzincan and Sivas provinces reflected the prevalence of bushy and early maturing accessions. Information provided herein comprehensively explored the occurrence of

“…These differences in the antioxidant activity of common seeds grown in different years have been previously explained to be influenced by environmental variations, crop management practices, and genetic differences [55]. Frequency distribution reflected that a good number of landraces acquired TEAC contents similar to the results of earlier studies [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]. The ANOVA was performed within and across the four environments to evaluate the genotypic effect and explore the GEI for antioxidant capacity.…”

Antioxidants play an important role in animal and plant life owing to their involvement in complex metabolic and signaling mechanisms, hence uncovering the genetic basis associated with antioxidant activity is very important for the development of improved varieties. Here, a total of 182 common bean (Phaseolus vulgaris) landraces and six commercial cultivars collected from 19 provinces of Turkey were evaluated for seed antioxidant activity under four environments and two locations. Antioxidant activity was measured using ABTS radical scavenging capacity and mean antioxidant activity in common bean landraces was 20.03 µmol TE/g. Analysis of variance reflected that genotype by environment interaction was statistically non-significant and heritability analysis showed higher heritability of antioxidant activity. Variations in seed color were observed, and a higher antioxidant activity was present in seeds having colored seed as compared to those having white seeds. A negative correlation was found between white-colored seeds and antioxidant activity. A total of 7900 DArTseq markers were used to explore the population structure that grouped the studied germplasm into two sub-populations on the basis of their geographical origins and trolox equivalent antioxidant capacity contents. Mean linkage disequilibrium (LD) was 54%, and mean Genes 2020, 11, 36 2 of 17 LD decay was 1.15 Mb. Mixed linear model i.e., the Q + K model demonstrated that four DArTseq markers had significant association (p < 0.01) for antioxidant activity. Three of these markers were present on chromosome Pv07, while the fourth marker was located on chromosome Pv03. Among the identified markers, DArT-3369938 marker showed maximum (14.61%) variation. A total of four putative candidate genes were predicted from sequences reflecting homology to identified DArTseq markers. This is a pioneering study involving the identification of association for antioxidant activity in common bean seeds. We envisage that this study will be very helpful for global common bean breeding community in order to develop cultivars with higher antioxidant activity.

“…Several reliable marker systems including SSR and SNP markers have been developed and used to assess genetic structure and diversity in common bean from different geographical locations Burle et al 2010;Cortés et al 2011;Bitocchi et al 2013;Raggi et al 2013;Sharma et al 2013;Song et al 2015). Green bean and common bean accessions collected from different geographical regions in Turkey have been evaluated using morphological and molecular approaches (Balkaya 1999;Sarıkamış et al 2009;Khaidizar et al 2012;Ceylan et al 2014).…”

Genetic Characterization of Green Bean (Phaseolus vulgaris L.) Accessions from Turkey with SCAR and SSR Markers

Characterization, conservation, and utilization of genetic resources is essential for the sustainability in agriculture. Plant genetic resources are important for breeding efforts designed for the generation of new cultivars or for the improvement of existing ones. Green bean has been cultivated extensively in Turkey giving rise to local accessions through selection over time and adaptation to various environmental conditions. The objective of the present study was to determine the genetic relationships of green bean accessions collected from Kırşehir Province of Turkey, located at the central Anatolia. Within a population of 275 green bean accessions, 50 accessions were selected on the basis of morphological observations for further evaluation with SSR and STS/SCAR markers together with 4 reference cultivars of Andean and Mesoamerican origin. SSR markers selected on the basis of high polymorphism information content revealed the genetic relatedness of selected green bean accessions. STS/SCAR markers associated with bean anthracnose, common bacterial blight, white mold, halo blight, and phaseolin protein demonstrated the inheritance of resistance traits of local accessions at the selected loci. These findings may help better utilize genetic resources and furthermore are expected to facilitate forthcoming breeding studies for the generation of novel cultivars well adapted to the region.
